# MandatoryStreamCombination

`public final class MandatoryStreamCombination`
`extends Object` ``

java.lang.Object
↳ | android.hardware.camera2.params.MandatoryStreamCombination

Immutable class to store the available mandatory stream combination.

A mandatory stream combination refers to a specific entry in the documented sets of required stream `CameraDevice#createCaptureSession`. These combinations of streams are required to be supported by the camera device.

The list of stream combinations is available by invoking `CameraCharacteristics#get` and passing key `CameraCharacteristics.SCALER_MANDATORY_STREAM_COMBINATIONS`.

## Summary

### Nested classes
`class` | `MandatoryStreamCombination.MandatoryStreamInformation` Immutable class to store available mandatory stream information.

### Public methods
`boolean` | `equals(Object obj)` Check if this `MandatoryStreamCombination` is equal to another `MandatoryStreamCombination`.
`CharSequence` | `getDescription()` Get the mandatory stream combination description.
`List<MandatoryStreamCombination.MandatoryStreamInformation>` | `getStreamsInformation()` Get information about each stream in the mandatory combination.
`int` | `hashCode()` Returns a hash code value for the object.
`boolean` | `isReprocessable()` Indicates whether the mandatory stream combination is reprocessable.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

## Public methods

### equals

    public boolean equals (Object obj)

Check if this `MandatoryStreamCombination` is equal to another `MandatoryStreamCombination`.

Two vectors are only equal if and only if each of the respective elements is equal.

Parameters
`obj` | `Object`: the reference object with which to compare.

Returns
`boolean` | `true` if the objects were equal, `false` otherwise

### getDescription

    public CharSequence getDescription ()

Get the mandatory stream combination description.

Returns
`CharSequence` | CharSequence with the mandatory combination description. This value cannot be `null`.

### getStreamsInformation

    public List<MandatoryStreamCombination.MandatoryStreamInformation> getStreamsInformation ()

Get information about each stream in the mandatory combination.

Returns
`List<MandatoryStreamCombination.MandatoryStreamInformation>` | Non-modifiable list of stream information. This value cannot be `null`.

### hashCode

    public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by `HashMap`.

The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `equals(Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is not required that if two objects are unequal according to the `equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class `Object` does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int` | a hash code value for this object.

### isReprocessable

    public boolean isReprocessable ()

Indicates whether the mandatory stream combination is reprocessable. Reprocessable is defined as a stream combination that contains one input stream (`MandatoryStreamInformation#isInput` return true).

Returns
`boolean` | `true` in case the mandatory stream combination contains an input, `false` otherwise.
